The construction of space main facilities.
In addition, existing tube forming method mostly uses greatly plate straight forming to go out tubing, obtained pipe deformations amount mistake
Greatly, it is difficult to reach actual demand, composite board can not continuously shaped tubing out.
Therefore, it is badly in need of providing a kind of in-orbit forming method of tubing, can be realized the in-orbit quickly manufacture on demand of tubing.
Summary of the invention
The present invention is directed to above-mentioned problems of the prior art, proposes a kind of in-orbit molding die of tubing and molding side
Method realizes the in-orbit quickly manufacture on demand of tubing, and it is excessive, no to solve deflection present in existing straight forming method
The continuously shaped problem of energy.
In order to solve the above technical problems, the present invention is achieved through the following technical solutions:
The present invention provides a kind of in-orbit molding die of tubing comprising: upper mold and lower mold, wherein
The upper mold is located at the top of the upper mold；
The curvature of the input terminal of the lower mold is lower than the curvature of the output end of the lower mold；
The lower mold and the upper mold are bent upwards, and the shape of the upper mold is corresponding with the shape of the lower mold
Unanimously.
Preferably, the upper mold pushes until being bonded the lower mold when the in-orbit molding of progress tubing.
Preferably, plate inputs institute from one end of the upper mold and the lower mold when the in-orbit molding of progress tubing
It states between upper mold and the lower mold, when the distance of plate input is more than pre-determined distance, the upper mold pushes until patch
The lower mold is closed, the plate is exported from the other end of the upper mold and the lower mold, is shaped to tubing.
Preferably, the curvature of the lower mold is gradually got higher from input terminal to output end.
Preferably, the length of the upper mold is identical as the length of the lower mold.
The present invention also provides a kind of in-orbit forming methods of tubing, for what is realized using the above-mentioned in-orbit molding die of tubing
The in-orbit forming method of tubing comprising following steps:
S11: by plate from the input terminal of the in-orbit molding die of the tubing input the upper mold and the lower mold it
Between, so that the plate is advanced always, while heating to the in-orbit molding die of the tubing；
S12: when length of the front end of the plate beyond the in-orbit molding die of the tubing is preset length, upper mold
It pushes until being bonded with lower mold；
S13: under pultrusion effect, the plate after making pre-molding continues to form in the in-orbit molding die of the tubing；
S14: it cools down, is formed to plate after molding is continued in the output end of the in-orbit molding die of the tubing
Tubing；
Plate described in the above process advances always, and heats to the in-orbit molding die of the tubing always.
Preferably, the plate in the step S11 is Thermoplastic Laminates.
Preferably, the plate at the uniform velocity advances.
Compared to the prior art, the invention has the following advantages that
(1) the in-orbit molding die of tubing provided by the invention and forming method realize the in-orbit tubing in the process of rocket
Preparation, only need to by plate transport enter the orbit, not only eliminated delivery bottleneck and size limit, but also save in-orbit storage space,
It reduces costs, lays the foundation for the construction of space main facilities；
(2) existing plate straight forming goes out that tubing deflection is excessive, and obtained tubing is difficult to reach actual demand, and
To make plate, precompressed, drawing molding, rear cooling are gradually shaped to tubing, keep away the in-orbit forming method that the present invention uses at high temperature
The excessive problem of deflection in forming process is exempted from, the pipe workpiece quality molded is high；
(3) it is existing using plate straight forming go out tubing cannot it is continuously shaped go out tubing, and the present invention can be in plate
The continuously shaped tubing out of plate is completed in the king-sized situation of length, can be greatly improved production efficiency, be shortened the production cycle.
Certainly, it implements any of the products of the present invention and does not necessarily require achieving all the advantages described above at the same time.
